TIRE RIM Application filed May is,

. This invention relates to certain novel improvementsin' tire rims andis particularly adapted to such constructions as are employed inconnection with the Wheels of autoemotive vehicles and the like and theinven- 'tion has for its principal object the provision of an improvedconstruction of this character which will be highlyeflicient in use andeco- "nomical in manufacture.

The salient object of'our invention is to providea tire rim whichwill bearranged so that it maybe detachably mounted on'the felly of a wheelfinany approved or desired manner.

. 15 .Another objectof the invention is to pro- "vide a; rimconstruction adapted to receive a pneumatic tire which will be soarranged that it will/be separable to; facilitate tireinstallation andremoval, and to provide securing portions arranged to produce awedgin'gaction. w 1

Other objects will appear hereinafter.

g The invention consists in the novel combinationand arrangement ofparts to befherei'nfafte'r des'cribed' and claime 1 The invention willbe best understood by reference toi the 'accompa-nying drawings,

showing the preferred form of construction and'in whichz' f V Fig. 1 is.a side 'elevational view of a rim" constructed'in accordance with ourinvention; Fig. 2 is an edge elevational view, partly in section, of therim depicted'in Fig. 1;

Fig. '3 is a sectional detail view, drawn to substantially on the line33 on Fig l; 1 r Fig. 4 is a view takensubstantially on the line 4 -4;on Fig. 3;;and v Fig. 5 is a perspective detail view employed in thedevice. I Y

In-the drawing wherein we have illustrated the preferred embodimentofour invention, 10 indicates our-improved rim which is'preferablyformed of two sections 11 and 12. The section 11 includes'a tire flange13 and the 1 section 12 includes" a tire flange '14. The foregoingconstruction is' substantially similar to the arrangement of a rim whichis of a bolt 1 5 formed" in one piece,it being understood that 1928.Serial No. 278,324.

a pneumatic tire is adapted to be retained be- I tween the flanges 13and 14:. I

The embodiment ofthe inventionillustrated is intended to be mounted onthe felly of awheel. .The section ll'is preferably arranged on the innerside of the periphery of the felly While the section 12 is'preferablyarranged on the outer side of the periphery of the felly. These sections11 and 12 are secured on the felly in any'desired manner after they havepreviously been secured to get-her in a manner to be set forthhereinafter.

The surface of the section 11 disposed toward the tire, and adapted toengage the section 12, is recessed as indicated at 17 to provide ashoulder 18. The section 12 in- .cludes a lip portion 19 that isdisposed in the recessed portionl? to abut the shoulder 18.

The portion adjacent the recessed portion 17 is enlarged as indicatedat.20 and extends radially inwardly away from this recessed 'portion l7and has a recessed portion 21 provided therein onto which the shoulder22 on the section 12 is fitted. It will thus be seen that the portion ofthe section 11 disposed toward the section 12 is arranged to provide'astep-like surface including the shoulder 18, thebottomof the recessedportion 17 shoulder 23, and the bottom of the recessed portion 21,the-shoulder 23 being provided by said recessed portion 21 and beingadapted to be engaged with the shoulder 22 of section 12'. The section12 has a face'thereof disposed toward the section 11 arranged tocomprise 'a step formation which will co-operate Withthestep. formationon the section 11 and" these portions tend tosecurely inter-fit thesections 11 and 12.

1 *A-fia'nge 16 is provided on the inner surface of the section 11and'it has also been pointed out that, an inwardly'protruding port-ion20 is provided. A shoulder 24 is provided on the portion 20. At suitableintervals around the diameter of the rim, openings such as 25 areprovided in the portion 20 which open into thesho'ulder24. The extendingportion 22 is cut away at corresponding intervals to providerecessesadaptedto register with the openings 25.and'these recesses are.indicated hollowed out; as indicated at 32, and the in-' ner Wallportions 33 of these hollowed-out portions 32 are tapered and when theWedging members 30 are disposedin' lockingip'o- V 7 [steparrangement-provided thereon, said 1n- -ner2ring sectionhavlngopenmgstextendmg I sition these tapered surfaces 33 act on the'footiportio'n 34of-theportion lfllheportion in the region351of2theisection 12' is 'ta- -pered sand'iformed soithat f thesurfaceiofithe portion 36 of vthe 'Wedging' members 30' will co-operate?therewith and exert a "wedging action at the: same time the portions 33are exerting a Wedginglaction on'the portion 34.
